Preparing and Mounting Apparatus.
Fig. 267.—Mounting Apparatus.
1.—Ross’s instrument for cutting thin covering-glass for objects. This apparatus consists of a bent arm supporting the cutting portion of this apparatus, which consists of a vertical rod with a soft cork at one end. A brass arm at right angles carries the diamond parallel with and close to the main rod.
2.—Covering-glass measurer. To measure the thickness of covering-glass, place it between the brass plate and the steel bearing; the long end of the lever will then indicate the thickness on the scale, to 1⁄50-th, 1⁄100-th, or 1⁄1000-th inch.
3.—Brass table on folding legs, with lamp for mounting objects.
4.—Whirling table with eccentric adjustment for making cells and finishing off slides.
5.—Air-pump with glass receiver, 3½-inch brass plate for mounting objects and withdrawing air-bubbles.
6.—Improved table with knife for cutting soft sections. This consists of an absolutely flat brass table, with a square hole to receive the wood, or other matter, on a movable screw, which adjusts the thickness of the section.
7.—Smith’s holder with spring and screw for adjusting pressure when mounting objects.
